AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
425 PM MST FRI JAN 10 2014

.SYNOPSIS...HIGH PRESSURE ALOFT WILL MOVE OVER THE GREAT BASIN
TONIGHT THROUGH SATURDAY...FOLLOWED BY A PACIFIC STORM SYSTEM
SATURDAY NIGHT THROUGH SUNDAY.

&&

.SHORT TERM (THROUGH 12Z MONDAY)...STRONG NORTHWEST FLOW ALOFT
REMAINS OVER THE FORECAST AREA THIS AFTERNOON...AS YESTERDAYS
TROUGH EXITS TO THE EAST AND A RIDGE BUILDS OVER SOUTHERN
CALIFORNIA. THAT RIDGE WILL SPREAD INTO THE GREAT BASIN
OVERNIGHT...LEADING TO DECREASING WINDS IN THE MOUNTAINS AND SOME
CLEARING SKIES. FOR TODAY...THE MOIST WARM ADVECTION HAS LARGELY
BEEN A DISAPPOINTMENT WITH REGARDS TO PRODUCING
PRECIPITATION...WITH NEXT TO NOTHING IN THE VALLEYS AND RELATIVELY
LITTLE IN THE MOUNTAINS. DECREASED POPS QUITE A BIT FOR THIS
EVENING...BUT EVEN SO THE POPS MAY STILL BE TOO HIGH FOR THE NEXT
24 HOURS.

WEST-SOUTHWEST FLOW WILL INCREASE TOMORROW AHEAD OF THE NEXT
APPROACHING TROUGH. THIS WILL CREATE QUITE WINDY CONDITIONS IN
SOUTHWEST WYOMING AND THE HIGHER TERRAIN OF NORTHERN UTAH...AND
COULD PRODUCE WINDY CONDITIONS IN OTHER PARTS OF WESTERN UTAH IF
MIXING IS SUFFICIENT. STILL SOME CONCERN THAT THE SOUTHERLY
SURFACE GRADIENT ACROSS NORTHERN UTAH IS NOT GREAT TOMORROW...AND
DIRECTION OF 700MB FLOW DOES NOT MATCH WELL WITH SURFACE
GRADIENT...BUT NEVERTHELESS THE POTENTIAL FOR STRONG WINDS IN THE
NORTHWEST DESERT AND OTHER WESTERN VALLEYS IS STILL SIGNIFICANT
ENOUGH THAT AN INCREASED WIND FORECAST SEEMED THE BEST COURSE OF
ACTION. ISSUED A WIND ADVISORY FOR THE NORTHWEST DESERT...WITH
SPECIAL CONCERN WITH CROSSWINDS ACROSS INTERSTATES 80 AND 84...AND
POST-FRONTAL CROSS WINDS ON UTAH STATE ROUTE 30. OTHER LOWER
ELEVATION LOCATIONS WILL HAVE TO BE WATCHED FOR STRONGER
WINDS...INCLUDING IN THE EUREKA AREA.

ONSET OF PRECIPITATION WILL LARGELY COME WITH THE COLD FRONTAL
PASSAGE SATURDAY EVENING INTO SUNDAY MORNING. PRECIP TYPE IS
EXPECTED TO START AS RAIN BELOW 7000FT...BUT SHOULD CHANGE OVER TO
SNOW FAIRLY QUICKLY IN GOOD COLD ADVECTION. WITH THE COMBINATION
OF WIND AND SNOW...DECIDED TO GO WITH A WINTER STORM WATCH FOR
SOUTHWEST WYOMING AND THE MOUNTAINS OF NORTHERN UTAH. THERE IS A
CHANCE THAT VALLEY LOCATIONS WILL NEED ADVISORIES IN THE
FUTURE...BUT WITH WARM SURFACE TEMPERATURES EXPECTED BY SATURDAY
EVENING AND THE WEEKEND NATURE OF THE SNOW...THE IMPACT IS NOT
EXPECTED TO BE AS GREAT AS THE IMPACT TO TRAVEL IN THE HIGHER
ELEVATIONS.

AFTER A GOOD PERIOD OF SNOW FOR THE NORTHERN FORECAST AREA
SATURDAY AFTERNOON THROUGH SUNDAY MORNING...PRECIPITATION SHOULD
BEGIN TO TAPER LATE SUNDAY AS THE STORM BEGINS TO EXIT THE REGION.
SOME MOUNTAIN SHOWERS MAY CONTINUE THROUGH SUNDAY NIGHT IN THE
LINGERING MOIST NORTHWEST FLOW.

.LONG TERM (AFTER 12Z MONDAY)...HIGH PRESSURE WILL BUILD ACROSS THE
FORECAST AREA BEGINNING MONDAY. 700MB TEMPS WILL RAPIDLY WARM...WITH
BOTH THE GFS AND THE EC SHOWING 700MB TEMPS ABOVE 0C ACROSS THE
MAJORITY OF THE STATE BY WEDNESDAY. THE VALLEYS WILL NOT REALIZE
THIS RAPID WARMING...AND INVERSION CONDITIONS WILL RETURN. VERY MILD
AND SUNNY CONDITIONS ARE EXPECTED FOR THE HIGHER MOUNTAIN VALLEYS
AND MOUNTAINS WITH NO SIGNIFICANT STORM EVENTS ANTICIPATED HEADING
INTO NEXT WEEKEND.

&&

.AVIATION...CIGS AT THE SLC TERMINAL WILL REMAIN ABOVE 6,000FT
THROUGH THE OVERNIGHT HOURS. WINDS WILL BE PREDOMINANTLY FROM THE
SOUTHEAST THROUGH TOMORROW MORNING...THOUGH MAY BRIEFLY SHIFT TO THE
NORTHWEST FOR A PERIOD THROUGH 2Z. HOWEVER...IF WINDS DO SHIFT TO
THE NORTHWEST...THEY WILL REMAIN BELOW 7 KNOTS.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...WINTER STORM WATCH FROM SATURDAY MORNING THROUGH SUNDAY EVENING
     FOR UTZ007>009.

     WIND ADVISORY FROM 8 AM SATURDAY TO 5 PM MST SUNDAY FOR UTZ005.
